The invention relates to a method for producing salts of butyric acid, lactic acid, propionic acid, valeric acid, acetic acid, glycolic acid, sorbic acid, fumaric acid, formic acid, malic acid, tartaric acid, citric acid, derivatives of said organic acids and mixtures thereof, comprising at least the successive steps of: •i) culturing a microorganism in an appropriate culture medium comprising a carbon source and a nitrogen source, during a sufficient time to obtain a fermentation broth comprising the organic acid(s); •ii) pre-treating said fermentation broth comprising at least clarification of the fermentation broth and separation of organic acids by evaporation of the clarified fermentation broth and then condensation of the volatile fraction containing organic acids (CVAF); •v) adding inorganic bases to said CVAF •vii) eliminating the remaining water of the CVAF, and recovering the organic acid salts.
The present invention features improved methods for producing pantothenate compositions. In particular, the invention features methods of culturing microorganisms such that spray-dryable compositions of pantothenate are produced. Also featured are pantothenate compositions produced by the processes herein-described.
